U.S. Route 61/190 Business

US 61/190 Business was originally only US 61, with US 71 (the original US 190 in Port Allen) ending at the ferry landing, and State Route 7 (the old US 190) following US 61 along Government Street and then onto Jefferson Highway (current LA 73). State Route 7 turned east at the intersection with Old Hammond Highway towards Denham Springs. US 61 followed Jefferson Highway, also signed as State Route 1. When the US 61/190 Bypass was built around Baton Rouge, a traffic circle existed at the current cloverleaf intersection that defines the southern terminus of US 61/190 Business. State Route 7 was realigned onto Florida Boulevard, with the old route (Old Hammond Highway) being redesignated as State Route 7D. == Future ==

In May 2019, the Louisiana Department of Transportation and Development (LaDOTD) petitioned the American Association of State Highway and Transportation Officials (AASHTO) to reroute US 61/190 Business from its interchange with I-110 to the intersection of Chippewa Street and Scenic Highway, including the section through Baton Rouge, onto I-110 itself. AASHTO approved the route relocation contingently, questioning if a business route should be relocated onto an interstate or if the business route should be deleted between the two interstate intersections. As of December 2020, all Louisiana documents point to US 61/190 running on the pre-2019 alignment, with the exception of internal routings which show that the portion of Florida Street between I-110 and River Road having been transferred back to the City of Baton Rouge. Additionally, the application from LaDOTD to AASHTO mentioned that existing parts of the business route would be transferred in sections over time. Similarly, an extension of Interstate 49 was approved at the same meeting and has not been signed as such as of June 2019. ==Junction list==
